We first plot the data in a scatter plot. The scatter plot is used to identify the degree polynomial that most closely fits the data. One greater than the number of turning points would be the polynomial's optimal degree. We calculate the polynomial's regression equation and contrast the absolute values of its correlation coefficient to 1. To verify their similarity, we graph this equation in the same window as the scatter plot. We need to discover different coefficients for a better fit if the model does not adequately fit the data or if the correlation coefficient's absolute value is not near to 1.
